The sum of Emil’s and Rosa’s ages is 27 years. Nine years ago Emil was twice as old
as Rosa was then. How old is each person?

Answers

e + r = 27;
e - 9 = 2 x ( r - 9 );
So, e = 27 - r;
Then, 27 -r - 9 = 2r - 18;
18 - r = 2r - 18;
18 + 18 = 2r + r;
36 = 3r
Finally, r = 12 years (Rosa);
e = 27 - 12;
e = 15 years (Emil);

Alison is currently three times as old as Mike. 5 years ago, Alison was eight times as old as Mike. How old is Alison now?

Answers

21 because first of all let’s start with the fact that 5 years ago a was 8m. Let’s substitute 1 for m if m was one, a would be 8 (five years ago) both add 5, but 13 would not be 3 times older than 6. Let’s then substitute m for 2. Then a would be 16 because 8*2 equals 16. Both add 5 and you get 21 and 7. 21 is 3 time more than 7.

find the separate equations form the lins represented by 3x^2 + 10xy + 8y^2 + 14x + 22y + 15

Answers

3x^2 + 10xy + 8y^2 + 14x + 22y + 15 = 0

3x^2 is factorable only as 3x and x.
15 can be 15 * 1 or 3 * 5.
As a first guess, I place 5 and 3 in that order.
The coefficients of y are unknown so far.

= (3x + Ay + 5)(x + By + 3)

= 3x^2 + 3Bxy + 9x + Axy + ABy^2 + 3Ay + 5x + 5By + 15

(3B + A)xy = 10xy

(3A + 5B)y = 22y

A + 3B = 10
3A + 5B = 22

-3A - 9B = -30
3A + 5B = 22

4B = 8

B = 2

A + 3B = 10

A + 6 = 10

A = 4

3x^2 + 10xy + 8y^2 + 14x + 22y + 15 = (3x + 4y + 5)(x + 2y + 3)

The product of (3x + 4y + 5)(x + 2y + 3) is indeed
3x^2 + 10xy + 8y^2 + 14x + 22y + 15

Explanation:

Let
P = area of triangle ABC
Q = area of triangle ACD

The two areas mentioned above are in ratio 1.5:1 which basically means
P = 1.5*k
Q = 1*k
for some value k
Notice how P/Q = (1.5k)/(1k) = 1.5 which proves that P:Q = 1.5:1

We can find the value of k by determining the area of triangle ABC
P = area of triangle ABC
P = (base)*(height)/2
P = 36*10/2
P = 360/2
P = 180

If P = 180, then
P = 1.5*k
1.5*k = 180
k = 180/1.5
k = 120

Telling us that
Q = 1*k
Q = 1*120
Q = 120
Q = area of triangle ACD
area of triangle ACD = 120
note how P/Q = 180/120 = 1.5 so P:Q = 1.5:1

We'll use this area to find the base of triangle ACD which is AD

Area of Triangle ACD = (base)*(height)/2
120 = AD*10/2
120*2 = AD*10
240 = AD*10
240/10 = AD
24 = AD
AD = 24

A probability experiment is conducted wich of these can not be considered a probability of an outcome: a) 0.222 b) 8.2% c) 0.0234 d) 122.96% e) 5/3 f) 0.45%

Answers

Probability can only range from 0 to 1 and d) 122.96% and e) 5/3 is bigger than 1 so the answer would be d and e.

122.96% and 5/3 cannot be considered probabilities of outcomes in a probability experiment because they are greater than 1. Correct option is d and e.

In probability, the probability of an outcome must be a value between 0 and 1, inclusive. Therefore, any value less than 0 or greater than 1 cannot be considered a probability of an outcome.

Let's check each option:

a) 0.222 - This is a valid probability since it is between 0 and 1.

b) 8.2% - This can be converted to a decimal as 0.082, which is a valid probability since it is between 0 and 1.

c) 0.0234 - This is a valid probability since it is between 0 and 1.

d) 122.96% - This can be converted to a decimal as 1.2296, which is not a valid probability since it is greater than 1.

e) 5/3 - This can be simplified to approximately 1.6667, which is not a valid probability since it is greater than 1.

f) 0.45% - This can be converted to a decimal as 0.0045, which is a valid probability since it is between 0 and 1.

Therefore, options (d) 122.96% and (e) 5/3 cannot be considered probabilities of outcomes in a probability experiment because they are greater than 1. The other options are valid probabilities as they fall within the range of 0 to 1, inclusive.

S = √3*73.5 /4.5=7 (Khufu’s pyramid)

The volume of Khafre’s pyramid is about 9/10 the volume of Khufu’s pyramid. If Kristina wants to make the second model pyramid so its volume is 9/10 the volume of the first model pyramid, what volume should she make the second model pyramid?

This goes with the other questions! if you need information i can get that for you!
Also, could you work it out!

Answers

3/6 should b you answer answer

Final answer:

The volume will be of 6.3 for the second model.

Explanation:

The student is asked to calculate the volume of the second model pyramid, Khafre's pyramid, which is 9/10 the volume of the first model, Khufu's pyramid. The student has already calculated that, for Khufu's pyramid, S = √3*73.5/4.5=7. To find the volume Kristina should make the second model, we simply multiply the volume of the first model by 9/10.

Although the question does not provide the exact volume of the first model, we will assume the value of S given is the volume of Khufu's pyramid model. Therefore, the volume of Khafre's pyramid model should be 7 * (9/10) = 6.3.

This result is based on the proportion given between the two pyramids' volumes and is a straightforward calculation of this proportion.

Gene has a gasoline budget of $275 per month. He uses an average of $7 of gasoline each day he drives. Which of the following equations represents how much money is left in his gasoline budget after x days of driving?

Answers

Final answer:

The equation to represent how much money is left in Gene's gasoline budget after driving for x days is y = 275 - 7x, where x is the number of days Gene drives and y is the money left in the budget.

Explanation:

The equation representing how much money is left in Gene's gasoline budget after driving for x days can be expressed as y = 275 - 7x. Here, 275 represents the monthly gasoline budget, 7 is the cost of gasoline each day, and x is the number of days. If we plot y against x, we can visualize how Gene's monthly gasoline budget decreases by $7 for each day he drives.

This equation is a simple example of a linear equation, which describes a straight line in a coordinate system. The variable x is the independent variable (number of days driven) and y is the dependent variable (money left in the budget). The slope of the line (-7) represents the rate at which the budget decreases each day.

"write an equation in slope-intercept form of the line satisfying the given conditions."

The line passes through (-3,2) and is parallel to the line whose equation is y = 4x + 1.

How do I do this problem? Show all work.

Answers

The given line has a slope of 4.
This is because y = 4x+1 is in the form y = mx+b (m = 4 is the slope)

Any line parallel to the given line is also going to have the same slope of m = 4

Plug in m = 4 and (x,y) = (-3,2) and then solve for b
y = mx+b
2 = 4(-3)+b
2 = -12+b
2+12 = -12+b+12
14 = b
b = 14

So m = 4 and b = 14 means that y = mx+b turns into y = 4x+14

Final Answer: y = 4x+14

ANSWER

The given system of equations has no solution.

EXPLANATION

We write the two equations in the slope-intercept form,

[tex]y = mx + c[/tex]

The first equation is
[tex]2x - y = 7[/tex]

We make y the subject to obtain,

[tex]y = 2x - 7 - - (1)[/tex]

The second equation is already in slope intercept form.

[tex]y = 2x + 3 - - (2)[/tex]

We can see that the two equations have the same slope but different y-intercept. This implies that, the two equations will never intersect. Therefore the system of equations has no solution.

Answers

[tex]y = 4x + 12[/tex]
Joel would have to go at least 10 times per month to make the 50 dollars per month the cheapest one.

Answer:

First choice is cheaper.

Step-by-step explanation:

Joel could pay $50 per month for unlimited use or he could pay $12 per month plus $4 per visit.

Let the monthly visits be x

We can define this as :

[tex]12+4x> 50[/tex]

[tex]4x >50-12[/tex]

[tex]4x >38[/tex]

[tex]x> 9.5[/tex]

So, x can be greater than 9.5 means 10.

[tex]4(10)+12>50[/tex]

[tex]52 > 50[/tex]

Comparing both we can say that the first choice is cheaper.
